Measurements of the total cross section difference (Delta)(sigma)(sub T) in np transmission between 0.86 and 0.94 GeV

摘要

We present results of the total cross section difference Delta-sigma (sub T) (np) obtained in transmission measurements at the energies 0.86, 0.88, 0.91, and 0.94 GeV. The SATURNE II polarized beam of free neutrons obtained from the break-up of polarized deuterons was transmitted through the polarized Saclay frozen-spin proton target. The beam and target polarizations were oriented in the vertical direction. The present results agree with previous SATURNE measurements and improve the amplitude analysis 4-n the forward direction.
